One of the best signatures of nonclassicality in a quantum system is the existence of
correlations that have no classical counterpart. Different methods for quantifying the …

Quantum information theory is built upon the realisation that quantum resources like
coherence and entanglement can be exploited for novel or enhanced ways of transmitting …

We report an experimental investigation of quantum correlations in a two-qutrit spin system
in a single nitrogen-vacancy center in diamond at room temperatures. Quantum …

Nonlocality is one unique property of quantum mechanics that differs from the classical
world. One of its quantifications can be properly described as the maximum global effect …

By using the quantum-memory-assisted entropic uncertainty relation (EUR), we derive a
computable tight upper bound for quantum discord, which applies to an arbitrary bipartite …

A bstract In this work we study how entanglement of purification (EoP) and the new quantity
of “complexity of purification” are related to each other using the EP= EW conjecture. First …

Since both coherence and quantum correlations arise from the superposition principle and
can be regarded as resources in quantum information tasks, it is of significance to …

We propose a measure of nonclassical correlations in bipartite quantum states based on
local unitary operations. We prove that the measure is nonzero if and only if the quantum …

We propose a modified metric based on the Hilbert–Schmidt norm and adopt it to define a
rescaled version of the geometric measure of quantum discord. Such a measure is found not …
